IPC: E04G7/14
Filed: 1941-03-13
Abstract: 547,014. Scaffold clamp. MARSHALL, A. C. March 13, 1941, No. 3453. [Class 20 (ii)] A scaffold clamp of the type comprising a main body portion 1 with grooves to receive the scaffold tubes at angles and a pivoted clamping member 5 associated with each groove, has interengaging portions 16, 17 between the clamping member and the main body whereby the pivot of the clamping member is relieved of strain. The pivot pin 6 loosely fits the apertures in the projections provided on the parts, and the interengaging portions are provided at a position relative to an inward projection of the clamping member so that as the scaffold member is placed in position for clamping, the clamping member is tilted until the head 13 of a bolt carried by it rides up over an incline 12 on the body and behind a projection thereon and so automatically locks the clamping- member in clamping position. A projection on the body may serve as a rest for the clamping member when in open position and the body member may be formed in two relatively rotatable parts so that the angle between the scaffold members may be adjusted.

Abstract: Nitrogenous fibres are dyed or printed with; an aqueous preparation which contains a metallisable dyestuff, an agent yielding chromium or cobalt and an assistant that is capable of forming with water, or water and an additive, a system of two liquid phases having a miscibility gap, the amount of assistant used being within the miscibility gap, the miscibility gap occurring at even relatively low concentrations of assistant and then subjecting the fibres to a moist heat treatment without intermediate drying.  The metallisable dyestuffs must contain groupings capable of forming a complex compound with chromium or cobalt, for example o:o1-dihydroxyazo, o-hydroxy-o1-carboxyazo, o-hydroxy-o1-aminoazo groupings, vicinal hydroxyl groups in the anthraquinone nucleus, salicylic acid and hydroxyquinoline radicals.  Dyestuffs usually requiring a two-bath after-chroming process can be used in the present single-bath process.  Specified agents yielding chromium or cobalt are sodium, potassium and ammonium chromate, Cr and Co complexes with tartaric acid, lactic acid, salicylic acid and salicylic acid-sulphonic acid, cobalt ammine complexes of the formula [Co(NH3)6] Cl3, [Co(NH3)5 Cl] Cl2, [Co(NH3)5.H2O] Cl3, [Co(NH3)4.CO3] NO3. 1/2 H2O and the complex obtained when an excess of aqueous ammonia is added to cobaltous acetate solution and the excess ammonia is expelled on a water-bath in the air.  The fibres exemplified are wool which may be in the greasy condition; mixed fabrics of wool with cellulose acetate, polyester or cotton may be dyed by including an appropriate disperse or direct dyestuff in the aqueous preparation.  Advantageously a thickener is used such as alginate, British gum, tragacanth or carob bean ether.  The assistants employed in the examples are the condensation product of 1 mol coconut oil fatty acid and 2.25 mols diethanolamine with the elimination of 1 mol water, the product obtained by keeping the addition product of 9 mols ethylene oxide with 1 mol coconut oil fatty acid diethanol-amide and with 1.1 mols diethanolamine for 1 hour at 140-150 DEG C. and the addition product of 8 mols ethylene oxide with 1 mol of a specified p-octylphenol.

Title: Improvements relating to the discharge of liquids from centrifugal separators
IPC: B04B11/06
Filed: 1928-02-09
Abstract: 285,088. Aktiebolaget Separatar. Feb. 12, 1927, [Convention date]. Density separators.-A centrifugal machine for liquid separation has a central feed member A, and a discharge device, for the heavier component, consisting of tubes G which extend inwardly from the periphery of the drum; they then run close to, and approximately parallel to, the axis of the drum. As the tubes discharge close to the axis, loss of energy is reduced to a minimum. The lower ends of the tubes terminate in a ring H which helps to secure the pile of discs. The heavier component, for in- .stance skim milk, is discharged from the tubes G into the chamber K; the upper ends of the tubes may be bent backwards or the material may be removed to facilitate discharge. The cream discharges through the screw J, placed below the milk outlets, into the chamber L. A hole N may be provided in each tube G for cleaning purposes, or a channel opening inwards may be wholly or partly substituted for each tube. The top nut of the machine may approach close to the discharge ends of the tubes G. In a modification, the milk passes from the tubes into an annular recess T in the nut S and is discharged through vertical channels U or horizontal channels V. In another modification the lower side of the nut S forms a conveying surface for the discharged liquid. In another modification the tubes G are shortened and the cream screw J is arranged above the milk outlet.

Title: Improvements in micro-relays
IPC: H01H45/00
Filed: 1923-02-13
Abstract: 213,386. Kajino, I. Feb. 13, 1923. Electrocapillary relays.-In an electrocapillary relay adapted for actuation by very weak currents, e.g. in connection with a wireless receiving system, such currents vary the surface tension of mercury in a capillary tube with an expanded end, and the passage of the mercury into the expanded end effects the opening or closing of the controlled circuit. In one construction. Fig. 1, the mercury is contained in a glass tube 5, bent as shown to provide an inclined capillary portion 17 with an expanded end 34 immersed in the electrolyte, a mixture of sulphuric acid and glycerine, in an outer glass vessel 3. The tube 5 is inserted in an airtight plug 4 fitted in the vessel 3, and its upper end is fitted with a plug 14 supporting wires 13, 15 separated by an insulating tube 16. The lower end of the wire 13 is formed with a loop 12, linked with a loop 11 of an electrode 10 carrying a float resting on the surface 8 of the mercury, and the wire 15 extends beneath the surface 8. The terminals 20, 21 of the actuating circuit are connected respectively to an electrode 19 extending into the electrolyte and to the wire 15, and may be short-circuited by a high resistance 33. The wire 13 is connected to a third terminal 22 and the terminals 21, 22 are in a battery circuit including a bell 29. The actuating current causes the surface 18 of the mercury to rise into the expanded end 34, thus lowering the surface 8 and bringing the linhs 11, 12 into contact to close the bell circuit. The mercury in the end 34 is forced back into the capillary portion 17 by compressing a rubber pressure-regulating- bulb 30. In a modification, Fig. 2, the mercury is contained in a U-tube 35 with an inclined capillary portion 36, and the passage of the surface 18 of the mercury into the adjacent arm of the U causes a separation of the surface 8 from an electrode 10 thus opening the circuit of an electromagnet 38 and closing the bell circuit. The apparatus may be used as an electroscope.

Title: Improvements relating to motor vehicle fuel supply systems
Inventor: WHITE JACK M
IPC: F02B1/00
Filed: 1955-02-15
Abstract: 785,323. Carburetters. A.C.F. INDUSTRIES, Inc. Feb. 15, 1955, No. 4450/55. Class 7(3) [Also in Group XXIX] In a fuel supply system for motor vehicles, the flow of fuel from a pump to the float chamber 13 of the carburetter is controlled by a floatactuated needle valve 26 for maintaining a predetermined constant level of fuel in the chamber 13 during normal operation and a servo-operated valve 37 controlled by the needle valve is provided for permitting an increased fuel flow to the chamber 13 upon a drop in the fuel level below the predetermined level. Such an arrangement enables a relatively large main valve to be employed so that accumulated fuel vapour is quickly vented and the fuel pump operates immediately at full stroke. The needle valve 26 controls an outlet passage 29 in a guide 27. The valve 26 is operated by a finger 25 on a pivoted float arm 18. The main valve 37 is carried by a diaphragm 36 clamped between the float chamber cover 22 and a cap 40 and is pressed towards a seat 42 by a spring 49. A chamber 30 beneath the diaphragm 36 communicates with the fuel inlet through a passage 32 containing a restriction 34 of smaller dimensions than the passage 29 so that the chamber 30 is vented when the valve 26 opens and the fuel inlet pressure opens the main valve against the spring 49 The restriction 34 and the valve 26 may be designed so that the main valve does not open at low or idling engine speeds. When the main valve is open, fuel passes to the float chamber through a passage 45. In modifications suitable for existing carburetters, the main and pilot valves are arranged co-axially and horizontally in a housing screwed into a lateral aperture in the float chamber.

Abstract: 677,893. Discharge apparatus. STANDARD TELEPHONES & CABLES, Ltd. Feb. 21, 1949, No. 4656/49. Class 39 (i). The trigger electrode 15 in a cold cathode gasfilled trigger or relay tube, suitable for highspeed pulse operation, comprises a foraminated sheet positioned at a distance not any less than and not substantially greater than the length of the cathode fall of potential for normal glow discharge away from a main electrode 4. The nickel electrode assembly is mounted by means of mica sheets and supporting rods from a glass press 1 sealed in a conventional envelope 2. The plate electrodes 3 and 4, forming the main gap, are mounted on rods 5 and 6 welded to eyelets 7 and 8 clamped to mica sheets 9 and 10. The rods 5 and 6 pass through locating micas 11 and 12, which are spaced from the rear of the respective plates 3 and 4 by a distance less than the length of the cathode dark space, and thus function as field control plates to confine the glow discharge to the desired cathode surface. If desired, metal field control plates may be mounted in the same planes as either or both of the plates 3 and 4. The trigger electrode 15 comprises an apertured plate, mounted on mica sheet 12 by means of bentover portions 16 or 17 which are riveted to the sheet. The edges of the plate 15 about the apertures 18 are preferably left sharp during manufacture to assist in reducing the formative delay time of the trigger gap by concentrating the field at these edges before the trigger gap breaks down. Connections from plate 3 and trigger 15 to the pins 19 of a conventional valve base 20 are made by means of support-rods 21 and 22 and wires 23 and 24. The main gap electrodes may be connected so that one electrode functions either as the anode or as the cathode so that anodic or cathodic triggering may be used. The gas filling comprises 92 per cent neon, 1 per cent argon and 7 per cent hydrogen at a pressure of 100 mm. of mercury. Typical dimensions and operating data are given together with curves illustrating the glow discharge phenomena on which the design is based. Specification 677,884 is referred to.
